Deep Space planetary missions require a set of robust antennas with varying radiation
patterns in order to close the dynamic communications link over the mission life. This paper …

A horn antenna operating from 18 to 31 GHz, for use in a reflector system was designed and
fabricated using three methods. The first method used conventional machining from a block …

The paper considers the process of developing and manufacturing prototypes of antenna
devices based on printing technology. During the development of the model and its …

The placement of multiple antennas onto a single antenna boom on a spacecraft is often
done to meet size and mass requirements. On the Europa Clipper spacecraft, one particular …

Global Navigation Satellite Systems (GNSS) are widely used today for a plethora of civil and
defense applications, including navigation of flying or moving platforms. Galileo, GPS or …
